This is slapped and bodged together, don't expect anything.

howto

1. Prepare files:
   • Anything that @Stickers usually takes. Largest side 512, webp is good.
   • Files will be sent added in alphabetical order
   • Add emoji(s) to be associated with the sticker as a subextension to the name of the file: foobar.webp → foobar.✅.webp
   • Max stickers per pack: 50, max forwarded messages at once: 100 (50x image+emoji)
2. TGAPIKEY=5667087765:DYTSC_49ScNQHyUJijg5yXc9uc_5A2rto go run . <path to directory with files to send>
   • You can get a Telegram bot API key from @botfather
3. Send any message to the bot (and get spammed)
4. Start creating a new pack
   1. Send /newpack (or /addsticker) to @Stickers
   2. Follow the steps until you reach Alright! Now send me the sticker
5. Forward messages from the bot to Stickerbot.
   • First selection shall be a (sticker) image, last should be emoji(s).
6. It will take a minute, it seems like nothing was forwarded.
7. Send /publish (or /done) to @Stickers and follow the steps to complete pack creation.
